Simplified route extension systems and methods
Techniques are disclosed for systems and methods to provide simplified route extension and/or display for autopiloting mobile structures. A route extension system includes a user interface for a mobile structure and a logic device configured to communicate with the user interface. The user interface includes a display configured to display at least a portion of an established route for the mobile structure. The logic device is configured to receive a first user input indicating a position on a navigational chart, receive a second user input indicating the received position corresponds to an extended route for the mobile structure, determine at least one extension routeleg from an endpoint of the established route to the received position, and render at least a portion of the extended route on the display.
1. A system comprising:
a user interface for a mobile structure, wherein the user interface comprises a display configured to display at least a portion of an established route for the mobile structure; and
a logic device configured to communicate with the user interface for the mobile structure, wherein the logic device is configured to:
receive a first user input indicating a position on a navigational chart;
receive a second user input indicating the received position corresponds to an extended route for the mobile structure;
determine at least one extension routeleg from an endpoint of the established route to the received position;
render at least a portion of the extended route on the display, wherein the extended route comprises the at least one extension routeleg, a waypoint of the established route, and/or a routeleg of the established route;
detect a navigational hazard along the extension routeleg; and
determine at least one additional extension routeleg and corresponding extension waypoint configured to avoid the detected navigational hazard and maintain an endpoint for the extended route corresponding to the received position.
2. The system of claim 1 , wherein:
the established route is a single leg established route or a multi-leg established route.
3. The system of claim 1 , wherein:
the first user input consists of a first single user selection, and the second user input consists of a second single user selection.
4. The system of claim 1 , wherein the logic device is configured to:
render a selection indicator corresponding to the received position on the display before receiving the second user input, wherein the first user input comprises a user selection of the received position.
5. The system of claim 1 , wherein the logic device is configured to:
render a contextual menu on the display proximate to the received position, wherein the contextual menu comprises a route extension button, and wherein the second user input comprises a user selection of the route extension button.
6. The system of claim 1 , further comprising one or more navigational sensors for the mobile structure, wherein the logic device is configured to:
receive navigational data from the one or more navigational sensors; and
generate at least a portion of the navigational chart based on the received navigational data.
7. The system of claim 1 , wherein:
the navigational chart comprises cartographic data, sonar data, radar data, satellite image data, visible spectrum image data, and/or infrared image data;
the logic device is configured to render the navigational chart and a mobile structure indicator on the display; and
the mobile structure indicator is configured to indicate a position and/or orientation of the mobile structure relative to an orientation of the navigational chart as rendered on the display.
8. The system of claim 1 , wherein the logic device is configured to:
convert the endpoint of the established route to a waypoint of the extended route; and
render a waypoint indicator corresponding to the waypoint of the extended route on the display.
9. The system of claim 1 , wherein:
the mobile structure comprises a watercraft; and
the logic device is configured to generate control signals configured to autopilot the mobile structure according to the extended route using a steering actuator and/or a propulsion system for the mobile structure.
10. The system of claim 1 , wherein the navigational hazard is detected using radar data or sonar data.
11. A method comprising:
receiving, at a user interface for a mobile structure, a first user input indicating a position on a navigational chart, wherein the user interface comprises a display configured to display at least a portion of an established route for the mobile structure;
receiving a second user input indicating the received position corresponds to an extended route for the mobile structure;
determining at least one extension routeleg from an endpoint of the established route to the received position;
rendering at least a portion of the extended route on the display, wherein the extended route comprises the at least one extension routeleg, a waypoint of the established route, and/or a routeleg of the established route;
detecting a navigational hazard along the extension routeleg; and
determining at least one additional extension routeleg and corresponding extension waypoint configured to avoid the detected navigational hazard and maintain an endpoint for the extended route corresponding to the received position.
12. The method of claim 11 , wherein:
the established route is a single leg established route or a multi-leg established route.
13. The method of claim 11 , wherein:
the first user input consists of a first single user selection, and the second user input consists of a second single user selection.
14. The method of claim 11 , further comprising:
rendering a selection indicator corresponding to the received position on the display before receiving the second user input, wherein the first user input comprises a user selection of the received position.
15. The method of claim 11 , further comprising:
rendering a contextual menu on the display proximate to the received position, wherein the contextual menu comprises a route extension button, and wherein the second user input comprises a user selection of the route extension button.
16. The method of claim 11 , further comprising:
receiving navigational data from one or more navigational sensors; and
generating at least a portion of the navigational chart based on the received navigational data.
17. The method of claim 11 , wherein:
the navigational chart comprises cartographic data, sonar data, radar data, satellite image data, visible spectrum image data, and/or infrared image data;
the method further comprises rendering the navigational chart and a mobile structure indicator on the display; and
the mobile structure indicator is configured to indicate a position and/or orientation of the mobile structure relative to an orientation of the navigational chart as rendered on the display.
18. The method of claim 11 , further comprising:
converting the endpoint of the established route to a waypoint of the extended route; and
rendering a waypoint indicator corresponding to the waypoint of the extended route on the display.
19. The method of claim 11 , wherein:
the mobile structure comprises a watercraft; and
the method further comprises generating control signals configured to autopilot the mobile structure according to the extended route using a steering actuator and/or a propulsion system for the mobile structure.
20. The method of claim 11 , wherein the navigational hazard is detected using radar data or sonar data.
